Other international students did not intend to use the increased allowance for J-Term travels. Kidus T. Asfaw ’13, said he knew of the two round-trip travel allowances but will not return to his home in Ethiopia in January. Instead, Asfaw will visit relatives in the United States...
When the scientists returned 11 days later, it took them only minutes to find the skulls of two adults, probably male. Six days after that, Berhane Asfaw of Ethiopia's Rift Valley Research Service found a third, the skull of a 6-or 7-year-old child, shattered into about 200 pieces. After years of painstaking cleaning, reassembly and study, the team was confident enough to tell the world that it had found the earliest true Homo sapiens--older by at least 1,000 generations than anything previously discovered. "It's not a modern human," says White...
Earlier discoveries at Gona, an Ethiopian site about 60 miles north of Bouri, had already shown that someone was using carefully manufactured stone tools in the area at about that time. Now Asfaw and White's team could make a circumstantial case that their species, A. garhi, was the gifted toolmaker. If so, this was a crucial bit of scientific sleuthing. In the 2 million years since the first human ancestor began to walk upright, nothing much had changed. Now something had. Rather than just using sticks and stones to leverage innate abilities--something done by plenty of animals, from...
Whoever did it, the creation of technology gave its inventors an astonishing advantage over other hominid species. Stone hammers and blades let them exploit carcasses left behind by other predators and permitted them to shift to an energy-rich, high-fat diet. "That," asserts Asfaw, "leads to all kinds of evolutionary consequences...
...fossils in hand date only to 200,000 B.P., and the oldest Homo sapiens to about 100,000. But some recent discoveries may help answer those questions. A 1 million-year-old cranium from Buia, Eritrea, for example, has characteristics of both H. erectus and H. sapiens. And what Asfaw and his colleagues call a "spectacular" partial cranium of the same age from Ethiopia should help as well when it's formally unveiled...
